## Is Reflective Set Theory stronger than \$\small {\mathsf{ARC}}\$?

By $$\mathsf{RfST}$$ its meant Reflective Set Theory exposited in this posting

I’ll pose two specific questions here:

1. Is $$\mathsf{ARC}$$ class theory a proper sub-theory of $$\mathsf{RfST}$$?

2. Is $$\mathsf{RfST}$$ equi-consistent with $$\mathsf{ARC}$$?
